Is there a way to clear a listbox of any text and color added programatically? So that everytime the vi is re-run will clear any previous data added previuosly.
Your "disabled code" will work as long as you are sure it runs before your loop. But the problem is that in your loop you are using insert into array. And if your ItemNames array is empty, then you are trying to insert an array at position -1 which doesn't exist. Try using Build Array instead.
